I use a USB null modem RS-232 serial cable and connect it with the X5000 serial port.

Further information: X5000 via null modem RS-232 serial cable

Ben wrote because of the issue with the onboard SD card today:
Anywhere is fine but I think it's easy. Coherent DMA is for historical
reasons a function of the processor generation, and as such a CONFIG
option.

So setting it according to CONFIG_NOT_COHERENT_CACHE will probably work
just fine.

Well at least I think so ... unless I'm missing some broken HW
somewhere I am not aware of.

Cheers,
Ben.

I had to create a patch for the possibility to select "CONFIG_NOT_COHERENT_CACHE" in the kernel config today.

not_coherent_cache.patch:

I will create a kernel with the kernel option "CONFIG_NOT_COHERENT_CACHE" for solving the issue with the onboard SD card.

Hi All,

I released the RC3-2 of kernel 5.4 for the AmigaOne X5000 today.

New:
Download: linux-image-5.4-rc3-2-X5000.tar.gz

Screenshot of ubuntu MATE 16.04.6 LTS on an A-EON AmigaOne X5000/40:

Please test it.

Thanks,
Christian

RC3-2 of Kernel 5.4 is up and running on my AmigaOne X5000

Image

Big picture: http://www.skateman.nl/wp-content/uploa ... 203428.png

In DMESG i found this IRQ error..

[ 5.041522] ptp_qoriq ffe4fe000.ptp-timer: IRQ index 0 not found
[ 5.046803] ptp_qoriq: irq not in device tree

I also found..but has nothing to do with this specific kernel, a change in the DPAA network driver.
Does not seems to creat a MII interface anymore which results in a non working MII-Tool utility.
This has been an issue for quite a while now and dont know where we lost this.... but i guess before kernel 5.0

skateman@X5000LNX:~$ sudo mii-tool

SIOCGMIIPHY on 'eth0' failed: Invalid argument
SIOCGMIIPHY on 'eth1' failed: Invalid argument
no MII interfaces found

Hi Skateman,

Many thanks for testing the RC3-2! :-)

Have you seen the same IRQ error messages with the RC3?

Cheers,
Christian

That's strange. If I use the old 5040 dtb file, then I don't see the DPAA Ethernet devices. If I use the new 5040 dtb file then I see both DPAA Ethernet devices but I get the following error messages:

Christian could you try this?

Make sure the ethernet cable of the onboard X5000 ethernet adapter is unplugged.
sudo ifconfig eht0 down (enter)
sudo ifconfig eht0 up (enter)
Now plug in a cable in the onboard X5000 ethernet adapter.
The adapter gets an Ip adress through DHCP and see if it works.

I will try it tomorrow.
